Abstract

The AA. set up 2 treatments including biological soil crusts (BSCs), natural BSCs without disturbance and disturbed BSCs (the top 30 mm of surface soil, including the BSC layer, was severely disturbed and completely removed), in a semi-arid environment on the Loess Plateau of China. Over the succeeding years, the natural recovery process of BSCs was qualitatively described and the soil water content at 0–90 cm depth of the two treatments was consecutively monitored. The results showed that : it is possible to recover moss-dominated biological soil crusts after disturbance; Crust disturbance decreased soil moisture and the effect gradually weakened with time; Crust disturbance decreased surface soil moisture but increased deep soil moisture; Crust disturbance degraded soil water conditions in the following 3–4 years. Therefore, artificial destruction of crusts in semi-arid region should not be recommended
